New information on the operations of embattled data analysis firm, Cambridge Analytica, has suggested that it played a controversial role in Nigeriaâ€™s presidential election in 2015.

A report by the London-based Guardian newspaper has revealed that Cambridge Analytica was hired by an unnamed Nigerian oil billionaire to work on the re-election campaign of then president, Dr. Goodluck Jonathan, and was paid an estimated Â£2 million ($2.8 million) to orchestrate a â€œferocious campaignâ€ against Muhammadu Buhari, then leading opposition candidate at the time.

Buhari went on to secure a historic election win in 2015. Before that, however, Cambridge Analytica reportedly attempted to furtively use hacked personal emails of Buhari, which were provided by Israeli hackers.

Cambridge Analytica staff working on the Nigerian elections reportedly met the Israeli hackers at the firmâ€™s London offices after which Alexander Nix, the recently suspended Cambridge Analytica CEO, allegedly asked staff to search the hacked emails for damaging information to be used against Buhari.

But, as The Guardian reports, â€œalarmedâ€ staff members refused to do so believing that the data was possibly obtained illegally.

For its part, SCL Elections, Cambridge Analyticaâ€™s parent company, has confirmed that it was hired â€œto provide advertising and marketing servicesâ€ for the Jonathan campaign but denied receiving or using hacked information during the campaign.

In the build-up to the elections, the Jonathan campaign notably focused on social media and public messaging questioning Buhariâ€™s educational qualifications and also, contentiously, his health status, setting off intense rumors and speculation.

The hacked emails were believed to have contained or referenced Buhariâ€™s medical records. Those rumors apparently had an element of truth as Buhari spent over 150 days on medical leave in the UK last year treating an undisclosed illness.

According to the Guardian, had Britain not voted to leave the EU, and Donald Trump not won the U.S. election, itâ€™s unlikely anyone outside Nigeria would have given a second thought to what went on during its presidential election campaign three years ago.

But the 20/20 vision of hindsight has cast a very different light on the events of early 2015, and a campaign that now seems to eerily prefigure what happened in the U.S. a year later. Many of the same characters, some of the same tactics.

â€œIt was the kind of campaign that was our bread and butter,â€ said one ex-employee. â€œWeâ€™re employed by a billionaire whoâ€™s panicking at the idea of a change of government and who wants to spend big to make sure that doesnâ€™t happen.â€

This was a standard variation on what SCL had done around the world for 30 years â€“ this time, with a twist. Weaponising information to harm an opponent was standard methodology.

It was a methodology honed and developed in the companyâ€™s defence and military work â€“ the fifth dimension of warfare, defined by the U.S. military as â€œinformation operationsâ€.

What was new, or at least new to those employees who have now spoken out, was bringing these techniques to the companyâ€™s election work.

Seven individuals with close knowledge of the Nigerian campaign have described how Cambridge Analytica worked with people they believed were Israeli computer hackers.

The sources â€“ who spoke to the UKâ€™s Observer newspaper over many months â€“ said the company was looking for â€œkompromatâ€ (Russian for compromising material) on Muhammadu Buhari â€“ at the time, leader of the opposition.

They said the hackers offered Cambridge Analytica access to private information about Buhari.

Their testimony paints an extraordinary picture of how far a western company would contemplate going in an effort to undermine the democratic process in a country that already struggles to provide free and fair elections.

But their claims have been disputed by the company, which is insisting it did not take possession of, or use any personal information for any purpose and did not use any â€œhacked or stolen dataâ€.

The company confirmed, however, that it had been hired to provide â€œadvertising and marketing services in support of the Goodluck Jonathan campaignâ€.

That work seems to have come about through Brittany Kaiser, a senior director at Cambridge Analytica, who would go on to play a public role at the launch of Nigel Farageâ€™s Leave.eu campaign, and a senior strategist on the Trump campaign.

Regarded by colleagues as a prolific networker, in December 2014 she was introduced to a Nigerian oil billionaire who wanted to fund a covert campaign to support Jonathan. The billionaire wanted total discretion.

An ex-employee said: â€œ[Kaiser] got a phone call. It was just before Christmas and she flew out to meet them in Washington DC. It was all a bit ridiculous. It was only six to eight weeks before the election and they were looking to spend nearly $2 million.â€

The election was a big deal. At stake, the future of the most populous country in Africa, and potential access to its lucrative oil reserves. The sitting president was favourite to win, though Buhari was doing unexpectedly well.

Not least because strategists for the All Progressives Congress (APC) had hired AKPD, once the firm of former Barack Obama strategist David Axelrod, which was pushing a slick, social media heavy Obama-esque message of hope.

â€œThere were a lot of scared millionaires worried that Buhari would get in. It was all very last minute. A team flew out to Abuja and put together a communications campaign. It was a straightforward, normal comms (communications) campaign in most respects,â€ the employee said.

Most but not all respects. The Observer has obtained an astonishing and disturbing video that Cambridge Analytica used in the campaign.

â€œComing to Nigeria on February 15th, 2015,â€ the voiceover said in the manner of a trailer for a Hollywood movie.

â€œDark. Scary. And very uncertain. Sharia for all.â€ And then it poses the question: â€œWhat would Nigeria look like if Sharia were imposed by Buhari?â€

Its answer to that question is certainly dark. And scary. Itâ€™s also graphically, brutally, violent. One minute and 19 seconds of archive news footage from Nigeriaâ€™s troubled past set to a horror movie soundtrack.

There are scenes of people being macheted to death. Their legs hacked off. Their skulls caved in. A former contractor said: â€œIt was voter suppression of the most crude and basic kind. It was targeted at Buhariâ€™s voters in Buhariâ€™s regions to basically scare the hell out of them and stop them from voting.â€

If Buhari wins, the film warns: women would wear the veil. Sharia law would be introduced. And the inference is, you may be macheted to death.

It wasnâ€™t just videos spreading fear. The Cambridge Analytica campaign team in Nigeria were jumpy too.

â€œIt felt risky, being there. There were various points when we were told we were in danger.â€ And in the Abuja hotel to which the team was confined in early 2015, rumours abounded.

The tales are Graham Greene-esque. The hotel was where slick western consultants, including a team from the now disgraced Bell Pottinger, partied with their Nigerian counterparts.

Mingling among them, western intelligence operatives â€“ state backed, or privately commissioned, nobody was quite sure.

And then there were the meetings: three sources told The Guardian about one that took place between Cambridge Analytica employees and two people they were told were Israeli intelligence operatives.

â€œThere was a two-hour meeting that took place in the hotel lobby between two senior campaign members and Israeli intelligence. After which they swept our hotel rooms for listening devices and said they would switch out our phones.

â€œThe story we were told was that there were intelligence agents from a number of different countries, including Israel and France, who were supporting Goodluck Jonathan and helping the campaigns.â€

There is no suggestion that Jonathan was aware of or implicated in this support. Another employee said: â€œBasically the Israelis didnâ€™t want [Buhari] to win.â€

A few weeks later, as the campaign was drawing to a close, there was another meeting at Cambridge Analyticaâ€™s London office.

An expert had flown in from Israel with a laptop, sources said.

Alexander Nix and Kaiser asked employees to take a thumb drive and download the contents on to their own computers.

The content was private emails and the information, they were told, related to Buhariâ€™s financial and medical records.

One employee who was present at the London meeting said he had initially assumed the visiting expert was Mossad or Israeli intelligence passing on what he called â€œlegtimate informationâ€.

But he began to realise this wasnâ€™t the case, he said, when he saw the reaction of his colleagues. One of them had â€œfreaked outâ€, he said. â€œHe was like, â€˜What the hell? I donâ€™t want anything to do with this.â€™â€

The witnesses were clear â€“ at least in their own minds. The information they were being shown had come from hackers.

Back in Nigeria, the team still on the ground found out what was going on from their colleagues in London. There was more â€œfreaking outâ€. This time with live, pressing concerns.

â€œThey were scared,â€ said a colleague who spoke to them while they were in the country. The campaign fixer, the person with local knowledge who had navigated them through the ins and outs of Nigerian politics, made it clear to them: they needed to get out of the country right away.

Cambridge Analytica had put them all in danger, they said. If opposition supporters found out, there was no saying what could have happened.

However, one member of the team missed his flight and instead of asking the office to re-book it, he got the first fight out â€“ to Dubai â€“ and put it on his credit card. â€œEveryone just wanted to get out as soon as possible.â€

But a spokesman for the company said its team remained in country throughout the original campaigning period and had â€œleft in accordance with the companyâ€™s campaign planâ€.

â€œTeam members were regularly briefed about security concerns prior to and during deployment and measures were taken to ensure the teamâ€™s safety throughout.â€

Elsewhere in Africa, Cambridge Analytica has confirmed working on Kenyaâ€™s elections in 2013 and 2017.

In a sting operation by UKâ€™s Channel 4 News, Mark Turnbull, managing director of Cambridge Analyticaâ€™s political division, said the company managed â€œevery elementâ€ of President Uhuru Kenyattaâ€™s campaigns.

Kenyaâ€™s 2017 elections were notably characterised by fake news and attacking commentary on opposition candidates mainly through Facebook and Whatsapp.

Beyond the continent, Cambridge Analytica is facing severe accusations of illegally harvesting millions of personal profiles on Facebook with its controversial methods linked to the UKâ€™s landmark Brexit vote and Trumpâ€™s election win in the U.S. The social network is also facing questions of its own over its data and privacy policies, compelling its co-founder, Mark Zuckerberg to apologise on Wednesday.

It is unclear how much of Cambridge Analyticaâ€™s work was based in Nigeria, Facebookâ€™s largest African market, was based on profile data of local voters mined on the social network.

According to The Guardian, there are multiple wider political questions about what went on in the Nigerian election of 2015 and the role western powers played: whether western political campaigners taking lucrative foreign contracts are contributing to the democratic framework of developing countries â€“ or helping to destroy them; if they are experimenting with methods and techniques that they later re-import back to more developed democracies.

Christopher Wylie, the Cambridge Analytica whistleblower who spoke to the Observer, called it â€œpost-colonial blowbackâ€.

â€œThe West found a way of fire-hosing disinformation into weak and vulnerable democracies. And now this has been turned back on us. This really is about our chickens coming home to roost.â€

Another said: â€œEverything the company did after the Mercers got involved was about refining a set of techniques that they would go on to use in the U.S. elections. These campaigns in other countries were experiments. They worked out how to harvest data and weaponise it. And they got steadily better at it.â€

What comes across most strongly, the sources said, is how little thought, if any, the senior directors in London had given to their employees and colleagues who became caught up in the activities, many of whom were in their early to mid-20s.

One member of staff who met the Israelis in the office on another occasion described them as â€œspecial forcesâ€ types. He said: â€œThey were cliche alpha males with a certain intellect. Looked military, very composed. They looked like they could beat the crap out of you.â€

Three years on, there is still stress in some of their voices when they recount these stories. Stress and fear and anger â€“ about the danger they were put in, and the lack of care shown towards them, the morally compromising position they were put in, the lack of knowledge they had about what sort of the company they would be working for when they took their jobs.

Itâ€™s why, despite the personal risks, so many of them agreed to speak.

â€œWhen I took that job, I did not sign up to any of this,â€ said one. Three years on, he is still angry and shocked and fearful. â€œYou donâ€™t know what this company is capable of,â€ he said.

In a statement, SCL Elections, the parent company of Cambridge Analytica, confirmed it had been hired in December 2014 in support of the Jonathan campaign.

â€œWe can confirm that SCL Elections was hired in December 2014 to provide advertising and marketing services in support of the Goodluck Jonathan campaign.â€

Asked specifically about the meetings in which staff described being asked to transfer personal information that they believed had been hacked, the firm said: â€œDuring an election campaign, it is normal for SCL Elections to meet with vendors seeking to provide services as a subcontractor.

â€œSCL Elections did not take possession of or use any personal information from such individuals for any purposes. SCL Elections does not use â€˜hackedâ€™ or â€˜stolenâ€™ data.â€
